Patent DE-2652904-A1 (DE)
Title: Auxiliary colour carrier coupling system - uses controlled oscillator with output modulated at quarter of line frequency
Inventor: HAUSDOERFER MICHAEL DR
IPC: H04N9/45
Filed: 1976-11-20
Abstract: Thecolour carrier coupling system is used to combine an auxiliary colour carrier with a half-line offset with an auxiliary colour carrier with a three quarter-line offset. A controlled oscillator (2) is operated at the frequency of one auxiliary colour carrier and its output is modulated by an AC voltage at a frequency which is one quarter of the line frequency (FH). One sideband of the modulated signal is compared in phase with the other auxiliary colour carrier (Fp), or a corresponding colour synchronising signal, with the oscillator (2) controlled in dependence on the phase difference.

Title: Radial blade high pressure blower - has inlet cone extending inside impeller to stabilise performance at low volumes
Inventor: KOHL HANS
IPC: F04D29/16
Filed: 1977-02-09
Abstract: The high pressure blower has a casing (11) within which there is an impeller (12) with radial blades (17). The impeller discharges compressed gas into the casing from which there is a compressed gas outlet. An inlet cone (20) set into the casing directs incoming gas into the eye of the impeller. The cone terminates in an out-turned flange (21) a small axial distance inside the impeller. Gas flowing in is therefore restricted to a part only of the axial depth of the blades. The front part (26) of the blades is traversed by a recirculating stream (28) of compressed gas. The front of the blade (34) is turned up to provide a smooth entry for this stream.

Title: Gas washer using electrostatic charge - injects oppositely charged water spray into smoke, and removes droplets and particles in separator
Inventor: LA ROCHEFOUCAULD GEORGES MATHI
IPC: B03C3/16
Filed: 1977-03-07
Abstract: The gas washer suitable for removing particles from smoke from foundries, furnaces etc. has a chamber (2) containing electrodes which charge negatively the smoke passing through the smoke conduits (1), and discharging into a vertical chimney (3). A water spray is injected through nozzles (4) through the chimney wall above the smoke entry. The droplets of the spray are fine enough to be in suspension in the gas, and are charged positively, so as to attract the particles. The nozzles are mounted inside tubes through the chimney wall so that a flow of air passes through with the droplets. At the top, the mixture passes through a branch pipe (5) connected to a separator (6) which retains the droplets, and passes the cleaned smoke. The injected spray also tends to absorb noxious vapours in the smoke.

Title: Identification system for bodies containing luminous material - uses intensity-wavelength distribution in emission spectrum for testing
Inventor: WEST MICHAEL ANTHONY
IPC: G07D7/12
Filed: 1977-03-24
Abstract: The identification system for bodies containing luminous or fluorescent material uses an induction radiation source for directing this onto a body in the testing station. The luminous material is induced to emit light radiation which in the event of different wave lengths is picked up at the same time by numerous optical systems (24, 25, 26) and passed to relevant photodetectors (18, 19, 20). Each optical system is associated with an optical filter (21, 22, 23) so as to transfer to the associated photodetector a different selected wavelength or range of wavelengths from those wavelengths which are sent to a different photodetector. Each photodetector produces an output signal which linearly changes its level according to the intensity of the emitted light ray which falls on this. The signal level of a photodetector is altered by attenuation or amplification and the altered signal level is compared with the signal level derived from a different photodetector.

Title: Land wheel assembly for reversible plough - has pivoted support arm whose swinging movement is controlled by stops adjustable with angular setting of frame
Inventor: GASSNER BENNO
IPC: A01B3/42
Filed: 1978-09-14
Abstract: The land wheel is supported on the reversible plough frame by an arm which pivots about a horizontal, transverse axis. There are stop elements on the pivot arm and on the plough frame. The stops (70, 88) are so arranged that in both plough working positions they are adjacent. The stops can be so moved relative to each other according to the angular setting of the plough frame that they assume a covering position in both working positions of the plough frame and a non-covering position during rotation. A setting device (70, 84) on the pivot arm transfers the pivot arm, in the final phase of turning into a position where the support wheel axle lies behind the vertical radial plane through the pivot axis.

Title: Gas-filled double glazing tightness test - by analysing test gas samples from tight container surrounding test specimen
Inventor: DARDAT KLAUS DIPL PHYS
IPC: G01M3/20
Filed: 1978-11-02
Abstract: Double-glazed windows and doors where the gap between the glass panes is filled with sulphur hexafluoride instead of air for better insulation, are tested for gas tightness by inserting the test specimen in a test container which can be sealed gastight and is located inside a water-filled and thermostated outer tank. Test gas which differs from the gas between the panes fills up the test container and any leakage is detected by analysing the test gas for traces of the other gas (by gas chromatography). This creates a reliable and simple tightness test of gas filled double glazed panes without any risk of broken panes through a long period. The actual temp. conditions can be closely simulated.

Title: Marine craft or fluid speed change measuring and indicating unit - uses differential amplifier with adjustable gain and null setting potentiometer to give percentage value signals
Inventor: JAKOB FRANZ DIPL ING
IPC: G01P5/07
Filed: 1978-12-29
Abstract: A device measuring the speed and percentage speed variations of a waterborne vehicle or flowing medium, e.g. wind, uses a new type of measurement method giving the same measurement resolution at low speeds as at high speeds. It uses the dynamo principle or that of generation of electrical pulses with integration giving an output voltage with speed related amplitude. This voltage drives the non-summing junction input of a feedback differential amplifier whose summing-junction input is connected to a variable compensation voltage source. The potential divider resistance values and the amplifier feedback resistor value are chosen so that, after adjusting the output indicator to the null position by setting the potentiometer, further changes in speed result in percentage speed change indications.

Title: Wind turbine with rotor blades of reduced length - has resilient couplings between all elements subjected to wind force
Inventor: GOSLICH HANS-DIETRICH
IPC: F03D1/06
Filed: 1979-04-04
Abstract: The wind turbine has a horizontal axis carrying a rotor hub with one or more rotor blades coupled to this via angled or resilient elements. The blades have a max. length of 3/4 of the rotor radius, with the length of the hub spokes corresp. extended, so that a small force is required to rotate the blades. All the elements of the turbine subjected to the wind force are coupled together via elastic elements, e.g. rubber mountings, springs or air cushions, while the mast which supports the rotor axis is dimensioned so that it is least flexible in the sense of its characteristic oscillation within the operating range.
Patent DE-2913880-A1 (DE)
Inventor: MITSDOERFFER JOERG
IPC: A47K10/38
Filed: 1979-04-06
Abstract: The holder for rolls of toilet paper has a base plate (1) with a hinge part (2). Linked to the latter are two bars each having a bearing journal (5, 6). The latter are inserted in a bearing bore (7). A bolt (8) serves for fixing the bearing journal (5). Said bolt is arranged in a bore of the hinge part (2) and engages with its end part facing the bearing journal (5) virtually without play in an annular groove (9). Two annular grooves (10, 11) are arranged in the bearing journal (6). Assigned to the two annular grooves (10, 11) is a ram (12, 13) which is mounted so as to be axially adjustable in the hinge part (2), said rams being forced towards the bearing journal by means of helical springs (14, 15). When the support bar is closed, the ram (12) engages in the annular groove (10) while the ram (13) is supported on the part (17) of the bearing journal located between the annular grooves (10, 11). This design leads to the holder being smaller in the region of the hinge part and thus to a reduction in the material expenditure. <IMAGE>
